Through trial and error I found a great way to make a crap ton of Grocshen. At the moment I am sitting on a bank of over 11k, and it would be more but after purchasing supplies, repairs, a new horse and horse gear. It will take quite a bit of trial and error but is extremely lucrative, and also helps with the Bandit Camp at Pribyslavitz quest.
1st go to youtube and watch youtuber ESO’s video on the hidden treasure locations, I was able to get 4 out of the 5, the last one is in a very hard lockpick chest, also these are where you will find the treasures of the Past goodies if you preordered. This will net you some great gear and a fair amount of coin in and of itself.
Now things you need, decent gear…try not to use plate, you need some mobility, the best bow you can currently use at your level, and most important, Better Piercing Arrows, which you can buy from the huntsman in the upper castle area of Rattay. I bought all 60 and its a whopping 360 grocshen, but the 150 piercing damage is amazing, almost a guaranteed kill shot to the chest at close range. I also bought a new horse with my gains and a new saddle with 4 bags, horse carryweight is now at 480lbs. Now basically all you do is stalk the bandits and Cumans at either the narrow bridge or the area where henry says you can launch a surprise attack. You just make them try and chase you away, so you can avoid a fight with multiple opponents. They dont immediately engage in combat but if you pullback your bow they are basically at point blank range with a better piercing arrow to the chest and drop like flies.
Loot their gear, transfer to horse, and repeat. Go back to Rattay, sell your haul, repair and repeat. Buy some savior schnapps, marigold, and lazarus potions just in case. you will definitely have the money for them.
I am not sure if the enemies respawn at the camp, I am thinking most don’t because at one point…no enemies were ever at the narrow bridge anymore. and on my last run through…I basically was able to kill everyone in both camps…and poison and burn arrows with out having to worry about getting caught.
A few general tips, I had so many archer duels while doing this. Use the trees to your advantage, basically a shield. Be careful of the bandits with halberds…they kill after like 3 hits but with no shield one or two arrows at center mass drop them.
You must really be careful of the Cuman and Bandit Captains, they have heavy armor and shields. I would recommend getting the headbasher skill on the strength tab. if give you a chance to knock out and opponent with a hit to the head, I have been saved by a glancing arrow shot off these bad boys’ heads that knock them out…then mercy killed with a mace to the face…lol
I plan on checking out if the bandit camp is still active after the quest battle, probably not but I am going to give it a shot. This was also a good way to level many skills, like archery, strength, speech, and main level.
Give it a shot and good luck!!!
